here is the sample app.

<?xml version="1.0" encoding="utf-8"?> <mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml"     creationComplete="onComplete();">     <mx:Script>         <![CDATA[             import mx.controls.Button;             private function onComplete():void {                 for ( var i:int=0; i<btns.numChildren; i++ ) {                     if ( i == 0 || i % 2 == 0 ) {                         Button(btns.getChildAt(i)).enabled = false;                     }                 }             }         ]]>     </mx:Script>     <mx:LinkBar id="btns">         <mx:dataProvider>             <mx:ArrayCollection>                 <mx:Array>                     <mx:Object label="Button 1" />                     <mx:Object label="Button 2" />                     <mx:Object label="Button 3" />                     <mx:Object label="Button 4" />                     <mx:Object label="Button 5" />                     <mx:Object label="Button 6" />                 </mx:Array>             </mx:ArrayCollection>         </mx:dataProvider>     </mx:LinkBar> </mx:WindowedApplication> 

Basically you access individual buttons using

libkBarInst.getChildAt(n) 

which gives you a Button. Hope that helps.
